Specification of Letters Patent.

Application filed September 18. 1905. Serial No. 278,978.

To all whom it may concern,.-

Be it known that I, RUSSELL HUFF, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have'invented certain new and useful Improvements in Pumps, of which the following isa specification.

The purpose of this invention is to provide a pump which will take its supply ofiluid from one source and distribute the Huid in equal quantities to different 4reservoirs or places where it may be required.

The invention is particularlv.designed for use in connection with motorriven vehicles for the purpose of returning the oil with which the machinery has been lubricated to oil cups or reservoirs located at dierent points; but the pump may be used for various other purposes. 'y

B means of m improvements the suppl of oil is evenly distributed regardless ofk di ferences in height of the oil-receptacles, an equal amount of oil being positively'forced into each of the delivery-pipes leading to such receptacles. y f

In the accompanying drawings, which illustrate the invention, Figure 1 is al sectional view through the apparatus on the line 1 1 of Fig. 2. Fig. 2 is a section on the line 2 2 of Fig. 1. Figs. 3, 4', 5, and 6 are. detail sectional views' taken through the distributing-valve in line with its various ports, showing, respectively, the successive positions of the valve during one complete cycle of operation.

Referring to the drawings, 1 indicates a driving-shaft provided, as shown, with a beveled pinion 2, by means of which the shaft may be driven directly or indirectly from the motor or engine. This shaft is rota.-

' table within bearings 3 and 4 in the base 5 of a suitable casing or housinga, which consti'- tutes the frame of thepump and incloses the working mechanism. Thisframe, as shown, comprises the base 5 and the part 6,- which is detachably connected therewith by screws 7, as shown, so that the working parts maybe readily inserted, removed, or inspected.

Upon theshait 1 is secured a worm 8, which engages :a worm-wheel 9, journaled upon a fixed stud 10,/which latter is secured within a threaded opening 1 1 in the side of the hollow frame or casing and-projects into the interior of the casing, asshown in Fig. 2. TheV worm 8 drives the worm-wheel in the direction indicatedby the arrow, Fig. 1, and a-v l suitable step-bearing 12 is provided at te end of the bearing 3, as shown, to take u thrust of the driving-shaft. A muti ated gear 13 and an eccentric 14 are also journaled.

upon the stud 10, and the eccentric, mutilated gear, and worm-wheel are secured together lby suitable means, such as the bolts or rivets 15, so that these three members will rotate in unison. Y

An eccentric plate 16 iits over the face and periphery of the eccentric, andA an arm 17, connected to said plate, has a lateral exten.- sion 17 a, which projects through an opening 18a in a pump-plunger'18. This plunger, as shown, is 'movable longitudinall within a pump cylinder ir the pump frame or housing. The opening :la is elongated, as shown, in order to permit. of lost motion between the' arm 17a and the plunger when itis desired to shorten the stroke of the latter, and this lost motion ma be regulated or entirely taken up by an a justing-screw 20, which extends longitudinally inward from the outer' end ofthe plunger and forms a stop for the arm 1751; The adjusting-screw is provided with a lock-nut 21.4 ln the drawings the adjusting-screw is shown in its innermost position, in whichlpo- .sition there is no lost` motion between the parts and the plunger makes its full stroke.

into the side of the pump frame or casing and having a central projection 26, which abuts against the end of the valve-stem. A mutilated pinion 27 is secured upon the valvestem, and -this pinion has teeth 28 atv four points arranged to' mesh with the teeth 29 upon the large mutilated gear 13. Between the sets of teeth 28 onthe pinion the latter has curved surfaces or lands 30, which are ada ted to engage the smooth surface 31 of the arge gear during the intervals when the' teeth of the gear and pinion are not engaged, so that the pinion is locked against rotation during such intervals.` This arrangement of mutilated interlocking caring is in common use and Well known an does not require an extended description or illustration. The large gear 13 has a few teeth at twopoints only, and these are diametrically opposite or barrel 19, whic is formed IOO .register simultaneously with the ports 32 arlild, T e

.one another thel arrangement 'being such yfthrou that ateachhalf-revolution of the large mutilated gear the mutilated pinion and the valve which is operated thereby will .be turned through an angle of ninety degrees Vand then'locked. The gears are so 'arranged that their teeth will engage and the pinion and the.va1ve will be moved wh-ile the pump,-v

plunger is changing its direction of 4movement and practically stopped after the corn-v pletion of each stroke. As the ear 1311s much larger than the pinion, this s ifting of Ithe valve takes place uickly at the time when there is, practicalill' speaking, no lonf gitudinal movement of t e pump-plunger.

The valve cylinder or socket 23 has an inlet-port 32 connecting with .a supply-pipe Y 34 at each halffrevolution of the valve.

33', and it 'has'a diametrically opposite port'v 34 connecting the interior ofl the pump-cylinder `with the valve cylinder orsocket.. Outlet-ports 35 and 36 extend from the valvesocket at-each side of the port 34 to a pair o f delivery-pipes 37 and 38, respectively. Thevalve 22 hasfa passageway 39 extendf ingd'iametrically through it and arranged to i valve alsohas two passagefways 40 and 41, as

shown,'extending'inwardly'toward the center ofthe valve and thence laterally in the same direction parallelffwiththe passage-way 39.-

I ngonfe position of the-valvejthe passage-way e 4 '1fis arranged to-connect the pump-cylinder port-34'with the delivery-port 35, as shown through anlangle of one hundred and eighty termediate wormcaring, eccentric, and cone valve 2 2 and the gearing e same are set with relation to -i one another so that the passage-way 39 will connect'thepump-oylinderport 3'4 with the in' let-port 32 atthefeomrnencement of each suction-stroke;

'While the eccentric is passing'over the dead-center and the pum piston is 'changing from the suction to t e succeeding compression stroke the mutilated gear and pinion intermesh andI the valve is.

given a quarterfrevolution, thus` bringing either. the passage-way 40 orthe passage-way 41 nregister with the pumpcylinder port 34 and one lefr-the delivery-ports, so ythat the plunger on'its inwardv stroke will force the iquid out through one ofthe delivery-pipes- The cycle of operations will be plainfrom an ins ection o f Figs. 3 to 6, inclusive. in .Fig'l 3 t e pump-plunger, as indicatedby the arrow, is supposed, to be moving. on the back Ward or suction stroke, and the fluid from the supply-pipe is free to HOW into the-cylinder the plungertherein and means for recipr eating the plunger, ofa valve havin af fp`as""v Asage-way adapted' to connect the in etfport Fluid will therefore be drawnlntothe pumpecylinder from the supply-pipe `.pression-'stro i 2.' Ina; fuidfdistributing pumphaving an with tlie ports 32 and 34. At the completion of the suctionstroke the valve is shifted through an angle of ninety degreesinto the position shown in Fig. 4, and the port-34 'is then 4connected to the delivery'epolt 35.

h the passage-.way 39 registers through the passage-way 41, so that" as the plunger movesl forward, as indicatedyby the arrow, the fluid will be forced from the7 um cylinderfinto the delivery-pipe 37." t ev completionof this 'compressionfstroke ofthe plunger the valve isagain shifted: thif'ugh an l v angle of ninety degrees, againbringing'the through passage-way 39 yin lne v with lthe that a further supply of -iluid may beinto the pump-cylinder? Atithe!) the pljun er.

moves backward' or outwardf,jas indicated v the arrow in said fi ure.- At-the completi,OILl of thisV suctionestro 'e vthe valve again' shifts through an angle of ninety degrees,; and the passa e-way140 then connects the port 34 so that lo n-the'succeeding compression-stroke of the .plunger the il'l'iidgwilly be delivered from.

the pum -cylinder into the delivery-pipe 38.:

us be seen that fluid wifl be delivered alternately into the delivery-pipes 37 3 8v y during the alternate compression-strokes of the plunger and that at each suction-stroke the valve willl connect the pumprcylindef' with the commoni'source .off supply-towitp.

the supply-pipe 33'. It will a thatthere is no opportunityl for the Huid to pass directly from one port to another, as the valve closes allof the portsi except the ones- 'so be noted,"v v

which are .in use at any one time.`
